20150352023 | PERIODONTAL DISEASE TREATMENT - The present invention for the first time discloses a method and a kit of parts for treating a periodontal disease, such as periimplantitis, gingivitis, periodontitis and/or periimplant mucositis, caused by microorganisms that colonize a tooth and/or implant surface at, above and/or below the gingival margin, and which reside in a biofilm either subgingival and/or supragingival, characterized by employing a surgical process leading to substantively removing, destroying, killing and/or disrupting and/or inhibiting growth and/or regrowth of a pathogenic biofilm at a site of a microbial infection in a patient suffering from a periodontal disease. Said method comprises, and said kit of parts comprises the means for; cleaning disinfecting and/or debriding the site of microbial infection mechanically and sequentially using first at least one cleaning and/or disinfecting agent with an immediate bactericidal effect, such as a NaClO solution, and thereafter at least one cleaning and/or disinfecting agent with a sustainable bactericidal effect, such as a CHX solution. | 12-10-2015 |
20150374455 | DENTAL SCALER - A dental scaler apparatus includes a low power transformer that is timed to the operating frequency of a detachable scaler insert connected to the handle of the scaler apparatus by selectively connecting corresponding banks of parallel adjustment capacitors by engaging corresponding switches coupled to each of the adjustment capacitors. | 12-31-2015 |
20160081764 | ULTRASONIC TIP FOR ULTRASONIC INSTRUMENT AND METHOD OF DENTAL TREATMENT WITH SAID ULTRASONIC TIP - The invention provides an ultrasonic tip in titanium for ultrasonic instrument, and further provides a method of dental treatment of peri-implantitis using an ultrasonic tip operable to cooperate with an ultrasonic instrument to transmit ultrasonic vibrations to a surface of a dental implant to be treated, said implant and said ultrasonic tip being made of titanium. The present invention guarantees a safe and complete debridement of most implants for the dental treatment of peri-implantitis, and for the maintenance of the implant surface after such a treatment. Designed in pure titanium, like most dental implant in the market, the tip of the present invention advantageously avoids the transfer of material on the implant and the alteration of the surface, thereby preventing the risk of bacterial recontamination. | 03-24-2016 |
